Hi to all,
I am working on design package using survival function.
First using PSM and adopting a weibull specification for the baseline hazard ,
I have got the following results(since weibull has both PH and AFT propreties
,in addition I have used the PPHSm command):

The survival package is a recommended package in R and contains survreg()
which uses the AFT definitions for Weibull survival. This is well
documented, and MASS (the book) has comparisons of PH and AFT
parametrization for a Weibull example.
I think you mean Frank Harrell's `Design' package.
I am trying to find a definition for the two-tailed exact binomial test but
have been unsuccessful. Can you help?

I use qda (package MASS) to obtain an object. If there is any

That makes no sense. qda objects do not have a density.

Dear R-helpers,
I want to merge several data sets into one single data set. For example,
there are three separate data sets like:
Set 1:
id age gender
01 12 M
03 15 F
04 19 M
...
Set 2:
id time x1
01 1 0.25
01 2 0.27
01 3 0.29
03 1 0.15
03 2 0.18
04 2 0.22
04 3 0.54

Set 3:

How does one define PDFs as yet undefined in R, such as the ex-
gaussian, the sum of two RVs, one exponential, one Gaussian? The PDF
would then be the convolution of an exponential PDF, dexp(), and a
normal, dnorm().
Kindly cc me in your reply to r-help.
Thanks,
Dear useRs,
I would like to summarize results of several tests in groups of two
columns - statistic, p-value, statistic, p-value etc. There would be
nice to add significance stars, but printCoefmat allows to do it only to
last column. Is there any way to do format such table without writing my

One way of creating fixed width output is to use 'sprintf' to create
the string and write the resulting data out. I used your input and
just selected columns 7-11 as an example. You will have to supply
whatever field width you want. I create a matrix and null out the row
and column names and
